Integrated Pest Management of Diamond Back Moth in Cabbage
Cabbage is usually cultivated all year round. In India, cabbage is grown at an area of 0.31 million hectares with an output of 6.87 million tons. It is grown in Gujarat, Uttar Pradesh, Odisha, Bihar, Assam, West Bengal, Maharashtra, Haryana, Jharkhand, Madhya Pradesh and Karnataka. Out of these states, West Bengal stands first in cultivation and production. Diamond back moth (DBM) is the major pest observed in cabbage. This pest was first reported in Haryana in 1914 and eventually spread to all states. In addition to DBM, aphids, leaf-eating caterpillars and cabbage head borer also cause crop damage. When the moth is in the resting stage, it appears as a pattern of diamonds; thus, it is known as the diamond back moth. Yellow-green larvae initially feed the chlorophyll content of the leaves and then make the leaf holes. In higher infestation, the whole plant defoliates and only the veins remain.
Management: o Raise tomato as intercrop. o Follow mustard or cress as trap crop. o Install Pheromone Traps @10 per hectare. o On initiation, spray neem seed kernel extract 500 ml/Acre (5%) or Bacillus thuringiensis bacterial powder @ 10 gm per 10 litres of water. o Add any detergent powder @10 gm per 10 litre of water to insecticidal or botanical, pesticidal solution, it enhances the efficacy. o This pest acquires and develops resistance against the pesticides very quickly and hence, change the pesticides at each spray application. o Collect & destroy the infested cabbage heads in the field after the harvesting. o Cotesia plutellae is a parasitoid and up to 60% parasitises to DBM. Avoid or delay the pesticide application if the population of this parasitoid is higher. o On higher infestation, spray Chlorpyriphos 20 EC @ 20 ml or Cypermethrin 10 EC @ 10 ml or Fenvalerate 20 EC @ 5 ml or Chlorantraniliprole 18.5 SC @ 3 ml or Chlorfenpyr 10 EC @ 10 ml or Cyantraniliprole 10 OD @ 3 ml or Diafenthiuron 50 WP @ 10 gm or Emamactin benzoate 5 SG @ 3 gm or Fipronil 5 SC @ 10 ml or Flubendiamide 20 WG @ 2 g or Flubendiamide 480 SC @ 3 ml or Indoxacarb 15.8 EC 5 ml or Novaluron 10 EC @ 10 ml or Thiodicarb 75 WP @ 10 g or Tolfenpyrad 15 EC @ 10 EC or Chlorfluazuron 5.4 EC @ 10 ml or Pyridyal 10 EC @ 10 ml per 10 lit of water.
